After attemps to sync, after re-installing passwords were lost
After reset of microsoft 10, passwords and toolbars were lost. Passwords and log-ins are gone....not insurmountable but annoying...planing to purchase a new computer soon....would like to be assured would not happen again

Do you have a C:\Windows.old folder that could possibly have your lot personal data?
- C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Profiles\<profile>\
"AppData" (XP: Application Data; Mac: ~/Library; Linux: ~/.mozilla) is a hidden folder.
You can copy files like these with Firefox closed to the current Firefox profile folder to recover specific data.
- bookmarks and history: places.sqlite
- bookmark backups: compressed .jsonlz4 backups in the bookmarkbackups folder
- cookies.sqlite for the cookies
- formhistory.sqlite for saved form data
- logins.json and key3.db (decryption key) for Passwords saved in the Password Manager
- cert8.db and possibly cert_override.txt for (intermediate) certificates stored in the Certificate Manager
- persdict.dat for words you added to the spelling checker dictionary
- permissions.sqlite for Permissions and possibly content-prefs.sqlite for other Site Preferences
- sessionstore.js for open tabs and pinned tabs
You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.
- Help -> Troubleshooting Information -> Profile Directory:
Windows: Show Folder; Linux: Open Directory; Mac: Show in Finder - http://kb.mozillazine.org/Profile_folder_-_Firefox
In the event that the passwords information is lost, you should record all information in a separate text file somewhere else on your hard drive, or written down. You can easily copy and paste if you need to do so. If you are concerned about someone else looking at that file, you can compress it using a password.
These can't get your data back, but will help in the future.
These add-ons can be a great help by backing up and restoring Firefox

FEBE allows you to quickly and easily backup your Firefox extensions, history, passwords, and more. In fact, it goes beyond just backing up -- It will actually rebuild your saved files individually into installable .xpi files. It will also make backups of files that you choose.
